A system for embedding credentials on an electronic document includes a task assignment device, a document database, a signature server and a credential server. The task assignment device generates an assigned task. The signature server generates a first signature request and a second signature request according to the assigned task. A first electronic device generates first signature information according to the first signature request. A second electronic device generates second signature information according to the second signature request. The signature server generates a first credential request and a second credential request according to the first signature information and the second signature information. The credential server transmits a first credential object and a second credential object to the signature server in response to the first credential request and the second credential request. The signature server embeds the first credential object and the second credential object into an assignment document in sequence. The present disclosure also provides a method and a device for embedding credentials on an electronic document.
